METAL CABINET.

Application filed August 18, 1921. Serial No. 493336.

To all whom it may concern:

Be it known that we, Amer J. E. LARSON, LEON C. Ln ROY, and VICTOR GRoNnERo, citizens of the United States, residing at Jamestown, inthe county of Chautauqua and "State of New York, have invented a new and useful Improvement in Metal Further objects are to improve metal cabinets or cases in the other respects herein- 1 after described and claimed.

In the accompanying drawings:

Fig. 1 is a front elevation of a filing cabinet embodying the invention.

Fig. 2 is a sectional elevation thereof, on

' an enlarged scale.

' Fig. 3 is a horizontal section thereof, on line 3-3, Fig. 2.

Fig. 4: is a sectional elevation of a portion thereof, showing the means for securing the top of the cabinet in place.

Fig. 5 is a horizontal section of a portion thereof, on line 55, Fig. 2.

Fig. 6 is a perspective group view of the 2 sides, top, bottom-and back and front frame of the cabinet, disassembled.

' Fig. 7 is a vertical section thereof, on an enlarged scale, on line 7"(', Fig. 2. Fig. 8 is a vertical section thereof,.on an enlarged scale, on line 8-8, Fig. 2. The cabinet of this invention comprises, generally stated, two sides A, a front frame member B, atop C, a bottom 1'), a back E, and drawer suspension or guide members F, which are separable from each other and may be packed. in a relatively small space and may be readily assembled. G represents su table drawers.

The cabinet has a pair of similar but oppositely arranged side walls or members 11, and is provided on its inner side with a vertically disposed retaining strip 12. The

retaining strips 12 which may be welded or otherwise suitably secured to or formed on the sides, are provided with front and rear. flanges which are spaced inwardly slightly from the sides A and respectively designated as 13 and l4. The front flanges 1,3 of the retaining strips are provided with a plurality of spaced notches 15. The rear edges of sides A are provided with flanges 16 extending inwardly or towards each other and the front edges are formed with rearwardly opening channels 17. In the construction illustrated, these channels 17 are formed by bending the front edges of sides A. inwardly and then rearwardly. 18 designates a pair of shelf supports, one on the inner side of each side A near its base and provided with a flange 19 spaced from the side A. As shown, the shelf supports are formed by bent metal strips welded to the sides and they terminate short of the front and rear edges of the sides.

The upper, inturned flanges 10 of the sides are each provided with a suitable number of spaced apertures 20. As illustrated in the drawings, flanges l0 terminate short of the front and back of the cabinet for a purpose to be hereinafter explained.

The front frame member B preferably comprises a. pair of upright, outwardly opening, channel side bars 21 connected by a plurality of drawer division or strike bars 22 and a bottom apron 23. The strike bars and apron v23 are preferably of the inwardly opening channel shapes shown and are welded or otherwise securely attached to the side channels so that the front frame B will be strong and rigid. The. side bars 21 are formed with apertures 24 between each pair of strike bars. When the cabinet is assembled, the forward portion of the side bars 21 seat in the channels 17 of the sides, as shown in Fig. 3, so that the front frame B ties the sides A together andholds their front portions rigidly in place;

The top C preferably has downwardly and inwardly bent front, side and back flanges 25, and the front flange carries a depending tongue 26, adapted when the parts are assembled, to engage behind the rearwardly extending front flanges 17 of the sides A. The side flanges 25 of the top are provided on their un er sides with a plurality of lugs 27 which engage in the oles 20 in upper flanges ,10 of sides A.

The bottom shelf D referably has front, rear and side depen mg flanges 28, the.

' side flanges being adapted to fit snugly in the spaces between flanges 19 of theshelf support and the sides'A, the rear and side flanges being cut away or notched as at 29 so as to permit of those portions of the bottom fitting over retaining strips 12.

The back E is provided with forwardly extending sideflanges 30 and also prefer;

4 lust/rated in Figs. 2 and 5. The. front end of each uide F is provided with a down-.

wardly irected tongue 35 which engages in one of the openings 24 in the side channel 21 of the front frame 13., The drawer guides are secured in position by means of suitable fastenings such as small screws 36 or the like, which enga e threaded holes 37 in front frame channe 21. The interlocking connections between the drawer guides and the channels 21, and stri s 12 carry the, weight of the guides an 'the' drawers thereon and only one small securing screw 36 for each guide is used, sim ply to prevent the disengagement of the interlocking'part's. The drawer guides may be of an usual or suitable construction.

Each tame, side bar 21 has a threaded hole 38 near the u per' end and the sides A have correspon ingly positioned holes 39, to permit the insertion of small screws or'tlie like to holdthese parts in their in terlocked relation. Each of the inwardly extending flanges 16 of the sides'is providednear 1ts upper end with a hole 40 and .similar purpose of securin the back E is provided with a pair of correspondingly positioned threaded holes 41 adapted to register with the holes 40 and toreceive small'screws or the-like for the the back and sides in their interlocked re ation'. The top 0 likewise is secured after bein interlocked with the sides of the cabinet by small screws or the like 42 inserted in registering holes iri'the contacting flanges of "the top and sides. 4

' The cabinet may be stored and shipped in knock-down condition and maybe easily assembled by placing the sides on the front frame, thenforcin :the front frame as far forward as possibe in the sides so vthat the forward portions of upright chanconnected nels 21' take their positions in the front channels 17 of the sides. The back E is then inserted downwardly between the sides, the side flan es 30 of the back takin under flanges 14.- of the retainin strips'an the back is shoved downward? lower end rests on the bottomv flanges 11 of the sides A. The back is confined bey until its tween the rear flan es 16 and the strips 12 on the sides, ant rigidly ties the two sides together. Bottom shelf D is then placed in position and engaged with shelf supports 18. The drawer suspension channels are then placed in position, as hereinbcfore described, and the sides, front frame and back are then secured together, preferablylby means of the four small screws, 4 I

as explained. Thetop is. then'placed in position by inserting the lugs on the top plate into the slots in the top flanges of the sides and pushing the top towards the rear of the cabinet until the rear edge of the top is flush with the back of the cabinet, after which the top is secured by means of-the small screws as described. Since the sides, back, front frame and top are joined, as explained, by interlockingparts thereon, these members are rigidly connected inde endently of the securing screws, and only. t e few small screws mentioned are required to hold the members in proper. relation. The, top and bottom arranged and connected as explained hold the cabinet in the intended rectangular shape.

We claim as our invention:
